Streamline Smitten Posted July 31, 2021 Share Posted July 31, 2021 I recently saw a '41 Zephyr with this button on the dash. It's straight above the starter button. It has the letters "SWF" on it. It appears it rotates because the letters are upside down. What is this button for? I have never seen it before. Link to comment Share on other sites More sharing options...
47clubcoup Posted July 31, 2021 Share Posted July 31, 2021 i believe it operates the windshield wipers. it works them on my car. Link to comment Share on other sites More sharing options...
Streamline Smitten Posted July 31, 2021 Author Share Posted July 31, 2021 That makes sense. "W" is for "Wipers", "S" is for "Slow", and "F" is for "Fast". What threw me is that normally that button has a little arm coming off of it. You grab the arm to rotate it to work the wipers. It doesn't have any letters on it. So now maybe someone can comment on why this has a different looking wiper button. Maybe it's from another year of car? Link to comment Share on other sites More sharing options...
47clubcoup Posted July 31, 2021 Share Posted July 31, 2021 i would keep it for now and take it off to turn it around , or turn the base so it looks better. Link to comment Share on other sites More sharing options...
Keith L. Posted August 11, 2021 Share Posted August 11, 2021 Keith here. The knob pictured is incorrect. Somewhere in it's history someone has exchanged it for a suitable replacement. I can tell by the photo ( speedometer )the car is a Zephyr, not a Zephyr Continental. The knobs for both were the same, however the Continental knobs have red lettering and the Zephyr ivory. The correct knob is the one on the left-hand side in the photo attached. Several years ago I wrote an article for the Way of the Zephyr outlining the interior knobs for the '36 through "41 Zephyr years. The B/W photo of the '41 layout is from the article.

Streamline Smitten Posted August 12, 2021 Author Share Posted August 12, 2021 So any idea what car this "SWF" button might have come from? Is it a 1946-48 HV-12? Link to comment Share on other sites More sharing options...
Streamline Smitten Posted September 6, 2021 Author Share Posted September 6, 2021 I think I may have figured out the mystery to this wiper switch that has "sWf" on it. The Zephyr authenticity manual says that electric wipers were optional on a Zephyr in 1941. As you know, vacuum wipers change speed based on engine vacuum (to the frequent chagrin of the driver). But with electric wipers you could conceivably have different speeds you can select (as all modern wipers do). So, while I have never seen this button before, I think this car probably had electric wipers. The "W" is for "wipers", the "s" is for Slow, and the "f" is for "Fast".

19tom40 Posted September 6, 2021 Share Posted September 6, 2021 That is a 1941 Ford windshield wiper knob. https://www.dennis-carpenter.com/product_search/20/1/2/?q=dash+knobs&globalfilter[custom1]=Car&globalfilter[custom2]=1941&globalfilter[custom4]= Link to comment Share on other sites More sharing options...
